The author seemed to be subtly mocking the idea. It seemed to be
suggesting that a Num instance for functions would imply the need for
constant number functions, which leads to difficulties. But I don't see
why one would have to take it that far.
In any case, I just tried the NumInstances package from Hackage and it
seems to work great.
